I agree. I think Cohen has spoken to Kitty, but they are not working together. What would be the benefit to Cohen? The risk of being ensnared in Kitty's possible reporting and market manipulation issues would be infinitely higher than any long-term benefit he would obtain. Besides, their goals seem somewhat at odds, as Cohen is (usually) a long-term investor who actually gets in there and gets his hands dirty "fixing" companies. Kitty, on the other hand, is all about the short-term momo. If he actually had long-term investment aspirations, he wouldn't be dumping that much money into short-term options.
Kitty is nothing but a star-struck fanboy who seems to desperately want Cohen's attention and admiration. He definitely has the first, but is unlikely to get the second in any meaningful way.
